.SPECIPICATION forming part of Letters Patent No. 357,795, datedFebruary 15, 1887.

Application filed March 16, 1886. Serial No. 195,432. (No model.)

To all 2072,0711, it may concern:

Be it known that I, GEORGE STEINSON, of Guttenberg, in the county ofHudson and State of New Jersey, have invented a new and Improved SpringBed-Bottom, of which the following is a full, clear, and exactdescription.

My invention relates to a spring bedbottom composed of a net-work ofcoiled wire springs connected to a suitable frame; and the inventionconsists, principally, in combining shackles with the springs, topreventthe same from being too far distended by heavy weight upon thebed, thus preventing the springs from injury and from being broken.

The invention also consists in forming the springs with hooks or loopsat each end to connect with chain-shackles; also, of a metal couplingformed with headed arms to connect the chains to form the net-work andto connect the net-work to the frame.

The invention further consists of the means employed for connecting thenetwork to the frame of the bed; and the invention finally consists ofthe'constmction, arrangement, and combination of parts, all ashereinafter de scribed and claimed.

Beferenceis to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of my new and improved bCdllOlliOlll complete.Fig. 2 is an enlarged detailed view showing the construction and thecombination of the springs; and Fig. 3is a sectional elevation of. thesame, taken on the line of Fig. 2.

A represents the frame of the bed, and B the elastic net-work attachedto the frame A by the metal straps G C. The frame A is, by preference,composed of four metal pipes, a, joined at their ends by the cornerelbow-couplings, Z) I), forming a rectangular frame.

The net-work B is composed of the coiled spring 0 and linked connectionsor short chains (1, that shackle the springs and prevent them from beingdistended too far. The chains (1 are connected together and to the frameA by the coupling-pieces c and the said metal straps G.

In order that the coils 0 shall be shackled by the chains (Z, I connectthe ends of the springs in the links of the chains by the end hooks, f,and pass the chain through the springs, giving some slack to the chain,which will permit each coil to distend the length of the slack and nomore, as the chains will then become taut and take the strain off fromthe springs. In this manner the springs are prevented from injury, nomatter how much Weight the bedbottoni may-be required to support.

The coupling-pieces c are preferably of malleablecast-iron and eachformed with a central body and npwardly-projeeting arms 0, (four or morein lllllllbtl,) and the arms 0 are each formed with a head or plateportion, 0', constructed to form a toggle-connection with the links ofthe chains (l and also (the outer ones in the net-work) with the metalstraps G, the same being slotted near their extremities, as shown at c,to receive the plate or head portions 0- of the arms, as shown clearlyin Figs. 2 and 53.

By detaching one end of each metal strap 0 from the couplers c thenet-work may be easily detached from the frame A, and as easily replacedby passing the straps over the bars of the frame and connecting themwith the couplings c.

Constructed in the manner described the bed-bottom is not only cheapandpractical, but is much more durable than the ordinary form ofbed-bottoms, and its elasticity when occupied will be practicallyuniform throughout the whole network B.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The short chains it, connected together bythe coupling-pieces e to form a net-work connected to the frame A by thestraps C, also connected. to the coupling-pieces e, in combination withthe coiled springs 0, one placed upon each short chain and connected. atboth ends to the chain, so that normally the chains will be held slackwithin the springs, substantially as described.

2. The coupling 0, formed of a solid central body having upwardly andoutwardly projecting arms 6, formed with flattened heads 6, to receivethe links of the chains, and the connecting-straps O, substantially asdescribed.

GEORGE STEINSON.
